Description

umrao STATES PATENT OFFICE.
CASEIN GLUE.
No Drawing.
To all whom it may concern:
Be it known that I, HENRY L. Pnns'rnronn'r, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Casein Glues; and, I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention provides a new composition of matter, herein designated as casein glue, but which, from its broader aspect, is an adhesive composition adapted to be used by itself or commingled with other substances, as an adhesive coating.
In this improved adhesive composition, casein is used as the adhesive base and it is commingled with dextrine, calcium oxide, sodium fluoride, sodium chloride, oil and resin. The sodium fluoride acts as a solvent of the casein, while the sodium chloride contributes, in a ineasure, to the keeping of the glue sweet and clean.
I have obtained a very highly eficient glue or adhesive material-by the use of the above noted substances in accordance with the following formula:
Parts. Casein to 75 Dextrine 2 to 8 Calcium oxide 1b to '20 Sodium fluoride 2 to 10 Sodium chloride 1 to 5 Cil 1 1 to 4:
Resin 1 5 it will be introduced into water to form an emulsion, and it is then, of course, that the chemical reactions that develop the adhesive compositions, will take place, 'After' the chemical reactions have taken place, the

emulsion is adapted to be used as glue or as a'coating to be commingled with other substances, such' as paint or calcimine,,which contain color pigments. When desired, however, the color-producing pigments may be commingled with the dry composition.
uniting with the casein, forming an insoluble compound known as calcium caseinate, and in combination with the sodium chloride, prolongs the liquid life of the solution. Sodium fluoride is a casein solvent but,'in the absence of the other ingredients, could not eflect a solution of the above colloids. The oil has the peculiarproperty of preventing the calcium oxide from changing into a calcium carbonate.
What I claim is: 1. An adhesive composition made sub: stantially in accordancewith the following formula, to wit: a
Parts. Casein 5( to 75 Dextrine 2 to 8 Calcium oxide 1() to 20 Sodium-fluoride 2 to. 10 Sodium chloride 1 to 5 Cil 1 to 4 2. An adhesive composition made in accordance with the following formula:
Parts. Casein 5O to 75 Dextrine 2 to 8 Calcium oxide 10 to 20 Sodium fluoride 2 to 10 Sodium chloride 1 to 5 Cil 1 to 4 Resin" 1 y In testimony whereof I aiiix my signature.
